Soluble salts on the surface ground in Guliya ice cap area change with climatic factors, es-pecially with dry and wet conditions. pH and electric conductivity values of the Guliya ice core dependon soluble salts originated from surrounding arid or semi-arid regions, therefore the dry and wetchanges can be approached by them. Results show that the approached dry and wet changes since thelittle ice age are consistent with that deduced from δ180 and accumulation rate.
